[Rtk-users] Truncation artifact recovery

[王治阵]

Hi,

Recently, I was using FDK algorithm for CBCT, but when I used  FieldOfViewImageFilter(), there were some truncation artifacts at the beginning and end of reconstruction results, which may be caused by insufficient data collection. Then, is there any algorithm in ITK and RTK that can eliminate truncation artifacts and restore the original field of view with some methods?

The small field of view is the truncation artifact, and the large field of view is the original field of view.
